USDA record comparison

Peanut butter calories and nutrition: 6 USDA records compared

The 6 exact records in this guide report 166–208 calories in the records' own listed source servings and 520–650 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.

What this page compares

Named source records, not one universal meal

This page includes every selected Feast nutrition record whose normalized USDA description begins with “Peanut butter” under the documented one-segment family rule. The records fall within Nuts and seeds. Exact descriptions remain visible so this grouping does not erase preparation, ingredient, or source-serving differences.

How this guide was assembled: Feast deterministically grouped exact USDA FNDDS records by their source descriptions. Every nutrient number is computed from the linked source fields; this page does not use generated or invented nutrition estimates.

Every number on this page comes from the exact linked record. Values are descriptive observations from the selected records; they are not personalized estimates, recommended portions, or measurements of a meal in front of you.

Serving values preserve each record's listed amount. Per-100-gram calories provide a shared weight basis. Dashes indicate that a value is not available, not that the nutrient is absent.

Portion analysis

Serving total and calorie density answer different questions

Every record uses a 32-gram source amount, which removes serving-weight differences inside this set but does not establish the size of your portion. Within the selected set, the source servings report 166–208 calories in the records' own listed source servings; the fixed-weight view reports 520–650 calories per 100 grams. A serving total and a per-100-gram value answer different questions, so neither should be substituted for the amount actually eaten.

To scale a record, divide the eaten grams by the record's source grams and multiply the listed serving values by that ratio. This assumes the eaten meal has the same composition as the matched record.

Preparation analysis

The dish name leaves ingredients unresolved

The record names distinguish lower sodium, lower sodium and lower sugar, lower sugar, reduced fat, and vitamin and mineral fortified. USDA formulation rows also identify 5 distinct source-input codes across the set, including peanut butter, smooth style, without salt, peanut spread, reduced sugar, peanut butter, smooth style, with salt (includes foods for usda's food distribution program), and peanut butter, smooth, reduced fat. These details can help select a closer record, but they do not isolate the cause of a nutrient difference or reconstruct a recipe.

A precise-looking result is only as specific as the record match and the portion information supporting it.

What changes the comparison

Four drivers worth checking before choosing a record

The visible dish name is a starting point. These details usually explain more of the variation in the selected source records.

01
Source-serving weight
The exact records list 32–32 grams, so serving totals can move even before composition is compared.
02
Named source variant
The set explicitly distinguishes lower sodium, lower sodium and lower sugar, lower sugar, reduced fat, and vitamin and mineral fortified; those words identify different records rather than optional SEO phrasing.
03
Nutrient profile
Across each record's own source serving, the displayed data span protein 7.1–8.3 g, fiber 1.6–2.5 g, sodium 5–173 mg. Different serving weights remain visible beside those values.
04
Formulation evidence
The source rows include 5 distinct input codes across this set. Input presence and weight describe standardized source formulations, not final plated proportions.

Record matching

How to find the closest description

Begin with the full source description rather than the shortest dish name. Check whether the named form—such as lower sodium, lower sodium and lower sugar, lower sugar, reduced fat, and vitamin and mineral fortified—matches the meal, then compare the listed source weight with the portion actually eaten. If the brand, recipe, toppings, cooking fat, or portion is known, keep that information with the estimate instead of assuming the generic record already includes it.

A practical matching checklist

Read the complete peanut butter source description, including preparation and additions.
Compare the listed source weight with the amount actually eaten.
Prefer a current package or restaurant source when a specific branded item is known.
Record toppings, sauces, cooking fat, sides, and substitutions that the selected description does not name.
